Usage Precautions; Ij Printer Long-Term Shutdown - Hitachi IJ RX2-SD160 Instruction Manual

1. USAGE PRECAUTIONS

1.1 Ink and makeup
(1) Ink and makeup replenishment
The printer employs an automatic ink/makeup replenishment system. While the printer is operated, the
ink reservoir automatically supplies the ink and the makeup reservoir automatically supplies the makeup
to the ink main tank at regular intervals. If the ink or makeup replenisher level is too low, an alarm is
issued. In this case, replenish the ink or makeup without delay.
(For the replenishment procedures, see Section 8.)
(2) Ink periodic replacement
For the replacement procedures, see "Technical Manual Chapter 6".
●While the IJ printer ink circulates for operations, it reacts with the atmospheric air elements and
deteriorates with time. Therefore, it needs periodic replacement. The guide for determining the
replacement interval conforms to the handling guidance of each ink.
*What is makeup? :
The makeup serves as the replenisher that makes up for the constituent loss due to ink
evaporation during ink ejection. It is also used as a cleaning solution.

1.2 IJ printer long-term shutdown

When the IJ printer is shut down for a long time due to production or other circumstances, the ink may
accrete inside of the printer and cause such problems as inability to be ejected or to be recovered. When
this occurs, the following actions must be taken.
1
Prevent accretion by operating the printer periodically.
Operate (eject ink) the printer for 1 hour or longer at least once during the "Shutdown Period
Guideline" shown in the table below.
2
Perform long-term shutdown storage work.
Before storage, drain the ink from inside the printer and fill the printer with makeup.
When restarting operation after storage, drain the makeup from inside the printer and fill the printer
with ink.
Refer to Technical manual "6.15 Long-term Shutdown" for detail.
